No spoilers will be allowed. The car will be allowed to run the

exchange as the top 4 finishers may be eligible to be claimed by another driver who
finishes on the lead lap or the track has the option to claim also. You can run a
Bert, Brinn or Falcon transmission if you run a crate motor.

IF THE RULES DON'T SAY YOU CAN DO IT... DON'T.

THIS IS A LOW BUDGET, AFFORDABLE CLASS AND MIDWAY INTENDS ON ENFORCING
THE RULES IN ORDER TO KEEP IT THAT WAY.

The rules are intended to ensure that sanctioned events are conducted in a manner that is
fair as possible for all competitors and consistent with the prompt finality in competition
results. On occasion, circumstances will be presented that are either unforeseen or are
otherwise extraordinary, in which strict application of the rules may not achieve this goal. In
such rare circumstances, officials, as a practical matter, may make a determination regarding
the conduct of the race, the eligibility of a competitor, or similar matters that is not
contemplated by or is inconsistent with the rules, in order to achieve this goal.

ALL CARS ARE SUBJECT TO OFFICIALS APPROVAL.
